A non-excitation tap changer is designed for oil-filled transformers operating at either 50Hz or 60Hz. When the transformer is not energized (meaning no winding is active), the switch can be adjusted either by hand or through an electrical signal to alter the tap setting, thereby modifying the voltage transformation ratio, allowing for precise control and stabilization of the secondary output voltage.
 
Specific introduction:
These switches consist of a switch housing and a control mechanism. Designed for oil-filled transformers operating at 50Hz or 60Hz frequencies, they can be mounted either on the transformer casing or the cover, allowing adjustment, setting, and modification while the transformer is energized.
1.This kind of electric off circuit tap changer applies to the single-phase, three-phase, combination oil-immersed transformer of electrical power .
2.The frequency of 50HZ,60HZ,rated voltage of 10KV,35KV,rated current of 30A~250A;the voltage-regulating places are: central part, neutral
point, can be directly fixed on the box-cover of the transformer
3.under the non-excitation condition regulating and changing.
